Hi Nicolas,

Thanks for fixing that last problem, that's great!

I've also come across a couple of other unexpected results exporting
other latex equations to pdf.  Examples are given in the attached org
file.  Both are quite trivial with easy work-arounds.  In both cases,
because the embedded png equations (displayed by C-c C-x C-l) are
formatted correctly, the problem in the exported pdf file might go
unnoticed.

Regards,

Paul
